Fig. 1'7 is an enlarged detail sectional elevation view of the cam control means for the thread holder and cut-offlthe cutter plate being broken away to show details of construction and operation. 7 V I The parts will be identified by their numerals of reference which are the same in all the views. I is thesewing machine base, 2 is the sewing machine arm, and 3 is the sewing machine head. 4 is the work holder plate which is movable over the base or bed of the sewing machine 'in all directions to carry the work. The plate is apertured at the center. Above'the work holder plate is superposed the work .presser shoe 5 within which is disposed the label presser foot 6. The work holder is carried on the arm"! of thework holder carrier and having elongated'teeth which are slidable back and forth on their driving pinion segments. I I

Rack 8| is engaged by driving pinion segment II which is secured to rocking sleeve I2 by set screw III. This sleeve is journaled in bearing I3 supported on plate I4 above the work holder carrier 3. When the pinion segment I I is rocked to and from it moves the work holder carrier forward and back and the work holder is free to slide to the right and left owing to the elongated teeth of the rack 8|.

Ihe rack 82 is actuated by pinion segment l5- which is carried on shaft I6 supported inbearings H on the plate I4 above the work holder carrier 8. The shaft i6 is provided with beveled gear ISI which is driven from shaft I8 carrying bevel driving gear 81. The shaft I8 is journaled within the sleeve 92 and is capable of rocking motion therein so that both the sleeve I2 and shaft iii are rockshafts.

It will thus be seen that by the actuation of the gear segments II and i5 successively, the work holder carrier 8 may be given a rectangular movement. By operating the same simultaneously in different relations, diagonal, circular or any desired form maybe given to the path of movement of the work holder carrier 8 and a corresponding movement, of course, given to the work plate 6 that is carried thereby. Any form of label or patch canthus be stitched, or the stitching may be in any design, as a written name ,or a trademarln The work is delivered to the sewing machine at the proper rate and proper time for stitching and the movement should be step by step to permit the proper action of the needle, and this should be done whether the movement is in straight lines, on the diagonal, or in curved or circular movement.

a I therefore provide for a step by step movement by a ratchet means which actuates cam means for eifecting the movement of the work holder. The ratchet action, of course, being in one direction, leaves the work at rest at the proper interval for stitching.

I9 is a double faced cam wheel supported on stub axle 20. This cam wheel is provided with ratchet teeth I9I on its periphery and also with cam groove 92 on the outer face and cam groove I93 on its inner face. The cam grooves are for actuating the segments. a a

The outer cam groove I92 actuates and rocks the segment I5. This is done by means of pitman 2I provided with a cam roller 2H which is acted upon by the cam groove. The cam groove I92 is provided with rests so that during a part of its movement the pitman is idle, and this is held in this position for rectangular movement of the work, while the opposite cam groove I93is acting. The rests on the cam grooves 192 and I93 alternate. The actuating parts drive the work holder alternately in opposite directions, thus in the machine here shown stitching a rectangular label.

The pitman 2i is connected to rocker arm 22 which is secured to the shaft I8 and rocks the same as the pitman is reciprocated. The pivotal connection of the pitman 2i to the rocker arm 22 is adjustable by set-screw 22! sothat the extent of the throw may be regulatedin that way, which enables the adjustment to different-sized labels as well as proper adjustment and location of the stitching within the margin of the label.

The pitrnan 2i is guided in its reciprocation by the guide 23 which is provided with a suitable groove and the guiding roller 23! which compels the pitman to move in a proper path in its reciprocation by the cam.

Cam groove 293 on the opposite side of cam wheel IS in like manner controls the segment II. This is done by precisely similar lever and cam connections to that for cam groove I92.

Pitman 24 with roller 2 engaging cam I93 is connected to a rocker arm 25 on the sleeve I2, the pivotal connection of the pitman being adjustable by thumb'screw 25h It will thus be seen that as the cam wheel is gradually rotated it will gradually feed the label in a predetermined rectangular position.

The: ratchet teeth I9! of the cam wheel are acted upon by a multiple pawl 26 which, because of the multiple engaging of the teeth, insures very fine adjustment and very fine action. This pawl is carried by rock-shaft ZBI having arm 262 disposed on swinging arm 263. This pawl is actuated by pitmanfl which is driven from wrist pin 2' on adjustable head 212 driven by the stitch feeding drive shaft 213, see Fig. 6. As the parts are rotated the pawl will feed the ratchet wheel a predetermined amount step by step at the right rate for stitching. The wrist pin 211 is adjustable back and forth from the center, to

regulate the throw, by the opposed set-screws. 214 a and'Z'IS, and means illustrated particularly in Fig. 10.

A multiple detent pawl 28, see Fig. 9, is pro vided to cooperate with the feed pawls. This is operated from rockshaft 22 having arm 282.. This multiple pawl is controlled from rockshaft 29. This rockshaft carries a cam finger 29! which actuates the slide 292 by engaging a pin 293 thereon. This slide is provided with actuating pins 294, 295 which act upon levers 2G2- and 282 to release the pawls 26 and the detents 2& for lifting them out of engagement with the teeth iSI of the ratchet wheel. A return spring 298 is provided for the slide 292.

, This means is actuated at the end of each operation to permit the back-setting of the cam wheel I9 so that the stitching at the beginning and at the end of afiixing each label may overlap. This is done in connection with the stop means. This is controlled by bar 39hereinafter' described.

I provide my improved machine with the usual standard construction of stop motion such as appears on the Union button sewer. I therefore do not detail the same further than tostate that the parts are-actuated by rcckshaft. 30 which is held in latched position by pawl 3 I, which pawl is tripped into the position indicated in, Fig. 8 to release the machine for stopping.

This latch is operated by the plunger 32 which is tripped by lug I99 on the cam wheel I9, see 8 and 9. When the machine is thus stopped the presser feet are raised by depressing the vertical actuating .bar 33-. V

The rockshaft 29 is supported in bearings 299 and actuated by link 33i on arm 29 on the said rockshaft 29.- When this rockshaft, as before described, has swung to the position for disengaging the pawls, the pin 29I on the arm 29I engages stop I95 on wheel 59, (see'Fig. 9) which, becausethe actuating and detent pawls are disengaged, can be set back several notches which sets the same correspondingly back of its normal starting position so that the first movement of the feed overlaps the final path of the needle forming an overlapping of the stitching at that point.

Of course, inorderto do stitching and work the fabric of the garment 34 should be inserted on the work plate underv the work presser foot 5, and inorder to do this it-is necessary to provide the presser foot twith means for elevating it, which here consists'of the lever35 pivoted at 35! to the arm of the sewing machine, the same being connected by curved link 352 to actuate the rockshaft 36 by connection to the rockshaft arm 36L This rockshaft arm 36l has a suitable connection 362 for elevating the work presser foot by rocking sha t 36 and its lug 363, see dotted lines in Fig. 3. The work presser foot is held yieldingly down by the springs 363 reacting againstthe shelf 3 carried bythe sewing machine head 3. It is clear that when the work presser foot is raised the fabric of the garment may-be insertedtherebeneath for clamping upon the work plate 4. This method of raising and lowering the work presser foot is common in this class of machines and I have therefore not detailed it at great length. I The work presser foot is provided with side arms which are spaced to correspond to the aperture in the work plate 4 therebeneath.

The work presser foot 5 is, as stated, made up of adjustable sides 5|, 52 which are adjustably secured in place by set screws 53, 54 on cross bar 55 at the rear." Bars 5| and 52 are attached at one end only. Between the sides 5!. 52 of the work presser foot 5 I dispose the label presser foot 6 carried on a spring pressed presser foot bar 31 which is disposed'in the sewing machine head 3 as is usual for'presser foot bars.

The presser foot baris provided with a cross bar 31! secured thereto by screw 312 through bracket H3 as seen particularly in Fig. 14, the bracket being, in effect, a spacer block as here shown. The cross bar 31! is moved rigidly up and down with the bar 31.

The label presser foot 5 is provided with a transverse slide groove 5| which embraces the lower edge of the cross bar 3' and is adapted to reciprocate on that slide bar. The bar 3?! is longitudinally slotted at 3H and a cross pin 52 engages the slot and holds the presser foot 6 in operative relation to the cross bar 378 and limits its movement thereon.

The label presser foot 6 is embraced by the side arms 5!, 52 of the work holder foot and the work holder foot is adapted to reciprocate back and forth in engagement with the said label presser foot. The label presser foot is made perfectly smooth like a flatiron on its under surface where it contacts with the label and it is provided with a main part 63 and an auxiliary cooperating forward part E i-which are connected together by a bracket arm 55, the space between these parts forming a stitching slot for the passage of the label presser foot along the sewing machine needle, so that a'laoel beneath will be held down by the presser foot, both in the front and the rear of the sewing machine needle in operation. This slot is, in practice, about of an inch wide.

The. under side of the presser foot is provided with longitudinal grooves 53 extending from front to rear through both the parted-i and 64. These are to accommodate the pair of label guides 39, 39 which are adjustably' secured by set screws 39! to the inner sides of the side members 5!,

52 of the presser foot. These guides are capable of adjustment back and forth to' vary the label space in the work p resser foot. The grooves 55% also accommodate the label stops 4!] which are alined with the guides 39 and are of such length that they project through the auxiliary part 64 of' the 'presser foot into. proximity with its forward edge.

The'under sides of the stops '45 and the forward ends of the guides 39 are serrated so that they enin its relation to the needle.

gage the fabric 34 securely. The label 4i is delivered down over the guides 39 by the feedpusher 42. (It may be done with the fingers.)v

a stop finger 422. in withdrawn position by spring 423 which is connected to the forwardly projecting finger 424 as seen in Fig. 1.

By adjusting the label slides 39, space can be left for a label of any length desired. By adjusting the side bars 55, 52 the; width of the label accommodated can be regulated and, of course, for eachlabel within limits the machine can be adjusted by adjusting the throw of the feed segments. If there is a material difference in size new cams on wheel !9 will needto be substituted.

The needle bar and needle are of usual construction and my improved label presser foot is adjusted in relation thereto as indicated particularly in Fig. 5 in its initial position. The label presser foot reciprocates from side to side sothat the slot therein travels laterally from side to side When the sides of the label are being stitched, the label presser foot stands still and the work presser foot reciprocates This pusher is secured to cross bar 42| provided with" The feed label pusher is held therebeneath in a forward and backward movement carrying the work under the label presser foot.

When other designs than a rectangle are being stitched, the labelpresser foot may be reciprocated from side to side at the same time that the work presser foot is reciprocating forward and back.

The label'presser foot, as pointed out, is car ried by the presser foot bar 31. This bar has a laterally projecting pin 314 at the top by means of which it is actuated. This is done by the slide 38 which has outwardly projecting pin 38! engaged by the slot 382 in the forward end of the lever 382. This lever 383 is fulcrumed at 384 and is connected by link 385 to the rear end of the lifting lever 35. Owing to the position of the fulcrum 384 the long end of the lever 383 raises the slide 38 at a more rapid rate than the lifting of the work presser foot, so that the label presser foot is elevated above the work presser foot when the presser feet are raised.

Thus the simple matter of raising the presser foot for the insertion of the fabric of a garment elevates the label presser foot to permit the introduction of a label. These levers are so timed that the label presser foot is raised first and, of course, can be kept in elevated position after the work holder foot has grasped the fabric to permit the introduction of the label under the label presser foot, when the presser foot can upon the'previously clamped fabric of the garment.

I provide my improved presser foot means with a special top thread cut-off and clamp. This consists of reciprocating'knife 43 having a beveled end 43! with a right-angle notched cutting edge 432, and a lower cutter 433. A spring 434 having screw 435 holds the knife 43 yieldingly against the bar 433. The knife is held in withdrawn position by spring 44 carried on screw 4M,

as seen inFig. l6.

The knife is operated from rookshaft 45 by rockshaft arm 45!, the end of which projects through a slot 434 in the rear end of said knife 43.v Rockshaft 45 is operated by compound lever mechanism consisting of arm 452 on the end of which is fulcrumed lever 453 the short end of which is connected to theelev'ating chain 46, see

be entirely released and the label can be clamped Fig. 13. The rear end of this auxiliary lever contacts with the upper surface of the presser shoe 5, thus making a compound lever movement of high power to insure the operation of the knife against the comparatively heavy spring.

This knife operating chain is operated by the vertically reciprocating slide 41 which is. notched at 41 I. for engagem nt by the dog 48 carried by presser foot actuating slide 33. pivoted at 4M on the said slide. The dog is provided with a stop pin 482 which projects forwardly through a slot 485 in the cover plate 49. This slot 49!: is. formed with a, cam projection 4-8.2 which engages the pin 482and withdraws the dog 48 from engagement with notch 4H, thus releasing the slide 41' and permitting the knife to. be withdrawn by the action of the spring 44.

Pivoted at the side of the head 3 is the guide 50 pivoted at Edi on the front side of the cover plate 43. This guide is controlled by cam lever 502 on pivot 533 on the feed cover plate 49, the

guide bar being supported by the bracket 5534 secured by the same pivot as the lever 502. When the lever 592 is operated and cams the guide 50 over to the right, as seen in Fig. 17, the straight edge of the same engages the pin 482 carrying the same straight up and preventing engagement of the notch 42H by the dog 48, so that by adjusting lever 592 it is possible to raise the presser foot and manipulate the same indefinitely without any action whatsoever on the cut-off knife which depends for its action on the engagement of the dog 38 with the notch 4' in slide 41.

The bottom knife and thread holder are not described herein as they are of usual construction and are not here detailed or illustrated.

I have now described the various parts of my machine and I will now indicate their operation by describing an evolution of the machine in the attachment of a label and what the different parts do in that behalf.

In the beginning the presser foot structure is elevated to the maximum by a down pull on the bar 33 by the chain or other means attached thereto. This reacts through link 33! on the arm 29" to actuate rockshaft 29. The operation of the rockshaft 22 actuates the cam finger 25H pulling down the slide 2292-, thereby through the actuating pins .284, 295 operating the levers 252 and 282 to release the pawls 26 and the detents 28.

By continued operation pin 29l on arm 29! strikes the stop notch !95 on the cam wheel 19, setting the same back a plurality of steps. The pressure on bar 33 is then sufliciently released to allow the work presser foot to engage the garment fabric inserted .therebeneath. When this is engaged the labelv presser foot is still in elevated position and a label is placed on the label guides 39 and fed to place by manipulation of. the pusher 42.

The label being thus in position the bar 33 is completely released and the label is clamped against the fabric, and the fabric securely clamped against the apertured work plate beneath.

The sewing machine is then started by a pull on the starting chain, which permits a complete evolution, stitching a label in place. The needle descends two or three stitches in advance of the stopping position and the segment gear ll feeds the presser foot, carrying with it the label in the work presser foot, forwardly underneath the label presser foot while the upper left hand portion, as illustrated in Fig. 5 is being stitched.

Then the cam for the segment H comes to rest and the cam for actuating the segment l5- is thrown into operation, and advances the label, work holder presser foot, and label. presser foot toward the left as illustrated in. Figs. 4 and 5, stitching the rear edge of, the label.

When the rear edge. iscompleted the cam at that side comesto rest and the cam for controlling the-segment, H is thrown into. work, reversing movement thereof and carrying the label work holder under the label presser foot to the rear, stitching the right hand end of the label, as seen in Fig. 5, until the corner is reached, that earn comesv to. rest and the segment [5 is actuated, carrying the whole structure to the right and stitching the front end of the label up to the left-hand lower corner, see Fig, 5.

Then the direction again changes by means of a segment It and the work holder slides the label and work under the label presser, foot, completing the stitching and overlapping the last two or three stitches at the point of beginning.

When the stitching is completed the presser foot is raised by a pull on the bar 33 which actuates lever 35 and this, through the link connection 335, operates thepresser foot, raising lever which operates on the label'presser foot, raising slide 38 to elevate the same.

With the structure as set in Fig.2, the elevation of the slide 38 elevates the dog 48 which engages in notch H! in the side of the slide bar 41. controls the cut-ofi knife, forcing the knife outward past the thread, hooking the same so that when the pin 432 passes up on the cam 492 the same will be tripped, the thread will be severed and the end will be clamped between the spring eat and the knife 43, as seen in Fig. 12. The garment with the attached label can then be removed, completing the evolution.

I desire to state that my structure can be greatly varied in its details without departing from my invention. I have shown the label presser foot rectangular in form, but as pointed out its form can be varied, its dimensions can be varied, and the label presser foot can be conformed to an aperture in the work presser foot and the cams organized to guide the work in proper relation to the needle. 7

I have shown various adjustments, all of which can be omitted when it is desired to use the machine for standard size, of which a large quantity is to be produced.

The actuating means for the work holder is available for various styles and kinds of work holder and presser shoes and while the details of one are especially adapted to the other, they may be used in other relations. So, also, the particular work holder, work presser foot and label presser foot can be made use of with the means for driving and controlling such work holder and presser foot devices as appears in my Patent No. 1,223,617, April 24, 1917.

The stitching of labels and patches for reinforcement on garments is, of course, a very important service to be rendered by my machine. However, it is frequently desirable merely to stitch forms such as rectangles and squares in portions of a garment or fabric for reinforcing or for various purposes.

I desire to claim my invention for that purpose as well as for the purpose of attaching labels and patches. By the proper construction and relation of parts it would also be possible to stitch directly and label it in that way, which, of

course, would be an important service for my improved machine. 1

I also desire to state that in the operation of this machine where labels are applied to heavy or stilt fabric, or to leather and other material of considerable integrity, the bottom work support ing plate can be dispensedwith' and thework presser foot can be madeuse of to force the work against the smooth needle plate, when the whole will be manipulated and very effective work done. This would be wholly impossible with light flexible fabrics where it is desirable and necessary to stretch the same across the apertured' work holder plate in order to make the same effective.

Having thus described my invention what, I

claim as new and desire to secure :by Letters Patent, is:
